Two days ago, the New Zealand Herald published an op-ed by Professor Emeritus Geoff Duffy, of University of Auckland, NZ, rebutting claims about emissions of methane by livestock contained in a report to our Parliament by the Parliamentary Commissioner for the Environment. Today in the Herald is a letter to the editor from one Paul Judge, of Hamilton, calling Prof Duffy a "climate denier", and challenging Geoff's statements about absence of warming. Read below, Geoff's article, and look at graphs that weren't in the Herald article. Then decide for yourself: who is the real denier?
